Lord Kṛṣṇa saw how the Kāliya serpent had polluted the Yamunā River with his terribly powerful poison. Since Kṛṣṇa had descended from the spiritual world specifically to subdue envious demons, the Lord immediately climbed to the top of a very high kadamba tree and prepared Himself for battle. He tightened His belt, slapped His arms and then jumped into the poisonous water.

SB 10.26.12, Translation:

Kṛṣṇa chastised the most poisonous serpent, Kāliya, and after humbling him He drove him forcibly from the lake of the Yamunā. In this way the Lord made the water of that river free of the snake's powerful poison.

Krsna, The Supreme Personality of Godhead

Pūtanā had smeared a very powerful poison on her breasts, and immediately after taking the baby on her lap, she pushed her breastly nipple within His mouth.

Krsna Book 6:

When Pūtanā was taking baby Kṛṣṇa on her lap, both Yaśodā and Rohiṇī were present, but because she was so beautifully dressed and showed motherly affection toward Kṛṣṇa, they did not forbid her. They could not understand that she was a sword within a decorated case. Pūtanā had smeared a very powerful poison on her breasts, and immediately after taking the baby on her lap, she pushed her breastly nipple within His mouth. She was hoping that as soon as He would suck her breast, He would die. But baby Kṛṣṇa very quickly took the nipple in anger. He sucked the milk-poison along with the life air of the demon. In other words, Kṛṣṇa simultaneously sucked the milk from her breast and killed her by sucking out her life. Kṛṣṇa is so merciful that because the demon Pūtanā came to offer her breast milk to Him, He fulfilled her desire and accepted her activity as motherly. But to stop her from further nefarious activities, He immediately killed her. And because the demon was killed by Kṛṣṇa, she got liberation. As Kṛṣṇa pressed her breast extremely hard and sucked out her very breath, Pūtanā fell down on the ground, spread her arms and legs and began to cry, "Oh, child, leave me, leave me!" She was crying loudly and perspiring, and her whole body became wet.
